Answer:
The reduced atom is Br.
Explanation:
- The oxidation-reduction reaction contains a reductant and an oxidant (oxidizing agent).
- The oxidation process is the process in which electrons are lost and produce positively charged ions.
- The reduction process is the process in which electrons is gained and negatively charge ions are produced.
- In the reaction of chlorine with calcium:
<em>2Na + Br₂ → 2NaBr,
</em>
<em></em>
Na loses 1 electrons and is oxidized to Na⁺. (Na → Na⁺ + e).
Br₂ gains 2 electrons and is reduced to 2Br⁻. (Br₂ + 2e → 2Br⁻).
<em>So, the reduced atom is Br.</em>
Answer:
Physical properties
Explanation:
These properties are the ones that you can observe or collect by your senses, for example the color, the odor, the sound, the texture, etc. In this case the substance is not going to change to a new one, it could be that is changing of state.
I would say the answer is... <span>C. AgNO3 + LiOH AgOH + LiNO3

Good luck!!
Answer:
Solid/freezing
Explanation:
Solid has the least energy of all of the phase changes and the more energy is lost the colder its gets then water turns into a solid called ice hope i helped!
Well, look up the atomic weights of copper and oxygen; add them appropriately; divide the total for the copper by the total for the molecule; then multiply by 100 to get it as a percentage.
